No Success

Hey everyone!! So my husband and I have been TTC for a while now and just the last 3 months did we know I had PCOS. I was placed on Metformin (recently stopped because I had 0 energy or interest to do anything & wasn’t having a period, once I stopped my period came) Tomorrow I meet up with my Dr on CD 3. What should I expect, would it be okay to ask for Letrozole or Clomid? Any advice would be appreciated!!
